Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Improperly escaped regular expression delimiters during domain matching validation can allow unauthorized domains to match cookie rules, potentially exposing sensitive session cookies to untrusted third-party servers.

Cookie Leakage: Non-RFC-compliant path matching allows cookies to be sent to subpaths that do not match the designated path boundaries, leading to unauthorized exposure of sensitive state.

Auth Bypass: Flawed cookie deletion logic deletes any cookie sharing a name when an empty cookie is removed, regardless of whether its domain or path matches, enabling unintended session destruction or state manipulation.
